Can you show us the actuall error message fromthe log file?

set ServerTracing to 0xFFFF in /etc/hylafax/hfaxd.conf and you should
get  logs of hfaxd logs in syslog (/var/log/deamon.log on debian I
beleve).

When the problem is happening, syslog output would be good first step.

After that, "strace" could be useful.    Find the $PID of the hfaxd
process and then:
	strace -tt -ff -o /tmp/hfaxd.strace -s 256 -p $PID

Show the problem a couple of times (you should see a new
/tmp/hfaxd.strace.XXXXX files appear for every hfaxd connection made),
and then stop the strace, and send all the /tmp/hfaxd.strace files to
me.  Make sure that the ServerTracing is set high before doing this
(seeing the logging in the log file makes it easier to follow the
execution in the strace output).
